Tokyo Marui Vsr-10 in good shape with miscellaneous upgrades to it, has a upgraded hop up, upgrades inner barrel, new cylinder and piston with new shears. Unfortunately due to this gun being passed around I dont know the specs of the inner barrel or the hop up, the hop arm are doesnt fit the new hopup so it doesnt have one, but it comes with the original hopup, rear sight, but it shoots well and has great performance. Come with 2 extra springs and trigger and piston combo. I'm open to receiving other gun just let me know what it is Or best offer
